The backtrace shows that Emacs is in infinite loop in
ccl_driver.  It seems that emacs-w3m does some code
conversion by CCL programs defined by itself.  And, it is
very likely that those CCL programs depend heavily on the
internal character representation.  That must be changed for
Emacs 23.

To emacs-w3m developpers:
  Please explain why it does code conversion by its own CCL
programs.  I'll be able to suggest a better way for Emacs
23.
